getAnimations method

@override List<CharacterAnimation> getAnimations(double progress, int charCount)

Generates per-character wave based on distance from text center.

Implementation

@override
List<CharacterAnimation> getAnimations(double progress, int charCount) {
  if (charCount == 0) return [];

  final curved = applyCurve(progress);

  return List.generate(charCount, (index) {
    final center = (charCount - 1) / 2.0;
    final dist = (index - center).abs() / max(center, 1.0);

    final returnT = sin(curved * pi);
    final localProgress = (curved - dist * 0.3).clamp(0.0, 1.0);
    final wave = sin(localProgress * pi);
    final eased = localProgress * (2 - localProgress);

    final scale = 1.0 + (scaleMin + (scaleMax - scaleMin) * wave - 1.0) * returnT;
    final dy = -height * wave * returnT;
    final opacity = 1.0 + (opacityMin + (1.0 - opacityMin) * eased - 1.0) * returnT;

    return CharacterAnimation(
      scale: scale,
      translation: Offset(0, dy),
      opacity: opacity.clamp(0.0, 1.0),
    );
  });
